MSDN renewal reported as spam

[Kenneth Porter <sh...@sewingwitch.com>]

I just found my MSDN renewal in my spam folder, and rightly so. It has all 
kinds of spam-sign in it. I'm pasting the offending headers below. 
Apparently these are being sent from some non-MS server with a long 
delivery delay, all-HTML. Any comments?

(My company name replaced with mycompany.)

(I just noticed my mail gateway is using its internal name in received 
headers. Off to fix....)
